Our Fragile X World collects data from families using online surveys and in-person studies. The studies cover topics such as sensory or behavioral challenges, health care experiences, and the impact of fragile X on families.

Fragile X Caregiver Burden Survey (2011)

In this survey, we talked to caregivers of people with fragile X. We asked them how caregiving affected their health, finances, and daily lives. We also looked at the health characteristics of children and adults with fragile X syndrome. We asked caregivers about the number of visits their child made to specialists and their child's use of medications.

National Fragile X Survey – Phase I (2008)

In 2007, we led the first national survey of families touched by fragile X syndrome. Over 1,250 families took part in the study. They answered questions about topics such as family adaptation, conditions related to fragile X syndrome, health experiences, and functional skills. This survey provided new knowledge about fragile X syndrome. It showed that parents are a valuable source of research information.
